When Frank carried Fido back to his mistress, he thought it his duty to tell Mrs. Leroy of the attempt to abduct the favorite.

Mrs. Leroy turned pale.

"Did the man actually take my little pet?" she asked.

"Yes, ma'am. He said it was his dog."

"The horrid brute! How could I have lived without my darling?" and the lady caressed her favorite tenderly. "How did you prevent him?"

"I seized him by the arm, and held him till a policeman came up."

"You are a brave boy," said Mrs. Leroy, admiringly. "But for you, Fido would have been stolen."

"The policeman said the man was a professional dog-stealer. He steals dogs for the reward which is offered."

"I was sure I could trust you with my pet," said Mrs. Leroy. "You deserve a reward yourself."

"I was only doing my duty, ma'am," said Frank, modestly.

"It isn't everybody that does that."

Mrs. Leroy rose, and, going to her bureau, drew an ivory portemonnaie from a small upper drawer; from this she extracted a two-dollar bill, and gave it to Frank.

"This is too much," said Frank, surprised at the size of the gift.

"Too much for rescuing my little pet? No, no, I am the best judge of that. I wouldn't have lost him for fifty times two dollars."

"You are very liberal, and I am very much obliged to you," said Frank.

"If I send again for a boy to take out Fido, I want you to come."

"I will if I can, ma'am."

For several days, though Frank was employed on errands daily, there was nothing of an unusual character. About eleven o'clock one evening (for Frank had to take his turn at night work) he was sent to a house on West Thirty-eighth street. On arriving, he was ushered into the presence of a lady of middle age, whose anxious face betrayed the anxiety that she felt.

"I have a son rather larger and older than you," she said, "who, to my great sorrow, has been led away by evil companions, who have induced him to drink and play cards for money. I will not admit them into my house, but I cannot keep him from seeking them out. He is no doubt with them to-night."

Frank listened with respectful sympathy, and waited to hear what he was desired to do in the matter.

"The boy's father is dead," continued Mrs. Vivian, with emotion, "and I cannot fill his place. Fred is unwilling to obey his mother. His companions have persuaded him that it is unmanly."

"I would gladly obey my mother if I could have her back," said Frank.

"Is your mother dead, then?" inquired Mrs. Vivian, with quick sympathy.

"I have neither father nor mother," Frank answered gravely.

"Poor boy! And yet you do not fall into temptation."

"I have no time for that, ma'am; I have to earn my living."

"If I could get Fred to take a position it might be a benefit to him," said Mrs. Vivian, thoughtfully. "But the question now is, how I may be able to find him."

"When did you see him last?" asked Frank.

"About three o'clock this afternoon I gave him seventy-five dollars, and sent him to pay a bill. I was perhaps imprudent to trust him with such a sum of money; but for a few days past he has been more steady than usual, and I thought it would show my confidence in him if I employed him in such a matter."

"I should think it would, ma'am."

"But I am afraid Fred fell in with some of his evil companions, and let them know that he was well provided with money. That would be enough to excite their cupidity."

"Who are the companions you speak of?" asked Frank.

"Boys, or rather young men, for they are all older than Fred, of lower social rank than himself. I don't attach any special importance to that, nor do I object to them on that ground; but they are, I have reason to think, ill-bred and disreputable. They know Fred to be richer than themselves, and induce him to drink and play, in the hope of getting some of his money. I have sent for you to go in search of my son. If you find him you must do your best to bring him home."

"I will," said Frank. "Can you give me any idea where he may be found?"

Mrs. Vivian wrote on a card two places,—one a billiard saloon, which she had reason to suspect that her son frequented.

"Now," said Frank, "will you be kind enough to describe your son to me, so that I may know him when I see him?"

"I will show you his photograph," said Mrs. Vivian.

She opened an album, and showed the picture of a boy of seventeen, with a pleasant face, fair complexion, and hair somewhat curly. His forehead was high, and he looked gentlemanly and refined.

"Is he not good-looking?" said the mother.

"He looks like a gentleman," said Frank.

"He would be one if he could throw off his evil associates. Do you think you will know him from the picture?"

"Yes, I think so. Is he tall?"

"Two or three inches taller than you are. You had better take the picture with you. I have an extra one, which you can put in your pocket to help you identify him. By the way, it will be as well that you should be supplied with money in case it is necessary to bring him home in a cab."

Frank understood what the mother found it difficult to explain. She feared that her boy might be the worse for drink.

She handed our hero a five-dollar bill.

"I will use it prudently, madam," said he, "and account to you for all I do not use."

"I trust you wholly," said the lady. "Now go as quickly as possible."

Frank looked at the two addresses he had on the card. The billiard-saloon was on the east side of the city, in an unfashionable locality.

"I'll go there first," he decided.

Crossing to Third avenue he hailed a car, and rode down-town. His knowledge of the city, gained from the walks he took when a newsboy, made it easy for him to find the place of which he was in search. Though it was nearly midnight, the saloon was lighted up, and two tables were in use. On the left-hand side, as he entered, was a bar, behind which stood a man in his shirt-sleeves, who answered the frequent calls for drinks. He looked rather suspiciously at Frank's uniform when he entered.

"What do you want?" he asked. "Have you any message for me?"

"No," said Frank, carelessly. "Let me have a glass of lemonade."

The bar-keeper's face cleared instantly, and he set about preparing the beverage required.

"Won't you have something in it?" he asked.

"No, sir," said Frank.

"You boys are kept out pretty late," said the bar-keeper, socially.

"Not every night," said Frank. "We take turns."

Frank paid ten cents for his lemonade, and, passing into the billiard-saloon, sat down and watched a game. He looked around him, but could not see anything of Fred. In fact, all the players were men.

Sitting next to him was a young fellow, who was watching the game.

"Suppose we try a game," he said to Frank.

"Not to-night. I came in here to look for a friend, but I guess he isn't here."

"I've been here two hours. What does your friend look like?"

"That's his picture," said Frank, displaying the photograph.

"Oh, yes," said his new acquaintance, "he is here now. His name is Fred, isn't it?"

"Yes," answered Frank, eagerly; "I don't see him. Where is he?"

"He's playing cards upstairs, but I don't believe he can tell one card from the other."

"Been drinking, I suppose," said Frank, betraying no surprise.

"I should say so. Do you know the fellows he's with?"

"I am not sure about that. How long has Fred been upstairs?"

"About an hour. He was playing billiards till he couldn't stand straight, and then they went upstairs."

"Would you mind telling him that there is a friend downstairs who wishes to see him, that is, if you know the way?"

"Oh, yes, I live here. Won't you come up with me?"

"Perhaps I had better," said Frank, and followed his companion through a door in the rear, and up a dark and narrow staircase to the street floor.

"It'll be a hard job to get him away," thought Frank; "but, for his mother's sake, I will do my best."
